Summary: Among Vietnam's unique folklore treasures, festivals are the most typical cultural area. A festival, which attracts a great deal of interest in social life, is an integrated form of activities including spiritual and material aspects, religious beliefs, arts and culture, the sacred and everyday life, and so on. Out of more than 9000 festivals in Vietnam, about 7000 traditional festivals are widely scattered across the country. Studying changes in the spiritual life of Vietnamese people through traditional festivals contributes to building spiritual life and building an advanced Vietnamese culture imbued with national identity. In order to ensure the effective organization and management of festivals, promote the cultural identity and diversity of national festivals, a scientific and comprehensive survey is needed, clarifying origins, characteristics, values, scale, and financial sources for organizing festivals; identifying viewpoints, criteria and classification methods on traditional festivals and modern festivals in our country, chaired by a specialized agency for scientific research. On the basis of the survey findings, the state authorities study and consider which types of festivals need planning, management decentralization, and elaboration of management regulations, mechanisms and policies consistent with the characteristics of traditional festivals and modern festivals.
